Subject: [PATCH v5 0/2] mmc: core: add a new property/caps2
Date: Tue, 7 Jul 2020 20:58:40 +0900 [thread overview]
Message-ID: <1594123122-13156-1-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
Some environment (like r8a77951-salvator-xs) is possible
to perform a full power cycle of the card in suspend via firmware
(PSCI on arm-trusted-firmware). However, the current MMC core
cannot issue Power Off Notification. This patch series can do it.
We discussed on the v3 email thread [1].

Changes from v4:
- Just add a new property/caps2 flag of MMC bindings to fix the issue.
https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=308795
Changes from v3:
- Modify regulator subsytem and regulator/fixed driver.
- Use regulator_is_enabled() instead of firmware API.
- Update R-Car Gen3 related dts files for the reference.
But, I have only tested on r8a779{5,61}-salvaltor-xs.dts.

Changes from v2:
- Fix typo of function name in patch2.
- Remove RFC.
https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=305523
Changes from v1:
- Use pm_suspend_via_firmware() API instead of pm_suspend_target_state.
- Modify the psci driver to call pm_set_suspend_via_firmware.
